Introduction to 8086 and Microsoft assembler

8086 Internal Block diagram

8086 is a 16-bit processor having 16-bit data bus and 20-bit address bus. The block diagram of

8086is as shown. (Refer figures 1A & 1B). This can be subdivided into two parts; the Bus Interface

Unit (BIU) and Execution Unit (EU).

Bus Interface Unit: The BIU consists of segment registers, an adder to generate 20 bit address and

instruction prefetch queue. It is responsible for all the external bus operations like opcode fetch, mem

read, mem write, I/O read/write etc. Once this address is sent OUT of BIU, the instruction and data bytes are fetched from memory and they fill a 6-byte First in First out (FIFO) queue.

Execution Unit:

The execution unit consists of: General purpose (scratch pad) registers AX, BX, CX and DX; Pointer registers SP (Stack Pointer) and BP (Base Pointer); index registers source index (SI) & destination

index (DI) registers; the Flag register, the ALU to perform operations and a control unit with

associated internal bus. The 16-bit scratch pad registers can be split into two 8-bit registers. AX AL,

AH; BX BL, BH; CX CL, CH; DX DL, DH.

Assembly Language Development Tools:

1. EDITOR:

Its system software (program) which allows users to create a file containing assembly instructions and statements. Ex: WordStar, DOS Editor, Norton Editor Using the editor, you can also edit/delete/modify already existing files. o While saving, you must give the file extension as .asm.

Follow the AL syntax while typing the programs

Editor stores the ASCII codes for the letters and numbers keyed in. o Any statement beginning with semicolon is treated as comment. When you typed your entire program, you have to save the file on the disk. This file is called source file, having an .asm extension. The next step is to convert this source file into a machine executable .obj file.

2. ASSEMBLER:

An assembler is system software (program) used to translate the assembly language mnemonics for instructions to the corresponding binary codes. An assembler makes two passes thro your source code. On the first pass, it determines the displacement of named data items, the offset of labels etc., and puts this information in a symbol table. On the second pass, the assembler produces the binary code for each instruction and inserts the offsets, etc., that is calculated during the first pass. The assembler checks for the correct syntax in the assembly instructions and provides appropriate warning and error messages. You have to open your file again using the editor to correct the errors and reassemble it using assembler. Unless all the errors are corrected, the program cannot be executed in the next step.

The assembler generates two files from the source file; the first file, called the object file having an extension .obj which contains the binary codes for instructions and information

about the addresses of the instructions. The second file is called list file with an extension .lst. This file contains the assembly language statements, the binary codes for each instruction, and the offset for each inst. It also indicates any syntax errors or typing errors in the source program. Note: The assembler generates only offsets (i.e., effective addresses); not absolute physical addresses.

3. LINKER:

Its a program used to join several object files into one large object file. For large programs, usually several modules are written and each module is tested and debugged. When all the modules work, their object modules can be linked together to form a complete functioning program.

The LINK program must be run on .obj file.

Mp and Mc Lab(17CSL48)

MSEC CSE Dept, Prepared By Nagayya S Hiremath Page 7

The linker produces a link file which contains the binary codes for all the combined modules. The linker also produces a link map file which contains the address information about the linked files.

The linker assigns only relative addresses starting from zero, so that this can be put anywhere in physical primary memory later (by another program called locator or loader). Therefore,

this file is called reloadable. The linker produces link files with.exe extension. Object modules of useful programs (like square root, factorial etc.) can be kept in a library, and linked to other programs when needed.

4. LOADER:

Its a program used to assign absolute physical addresses to the segments in the .exe file, in the memory. IBM PC DOS environment comes with EXE2BIN loader program.

The .exe file is converted into .bin file.

The physical addresses are assigned at run time by the loader. So, assembler does not know about the segment starting addresses at the time program being assembled.

5. DEBUGGER:

If your program requires no external hardware, you can use a program called debugger to load and run the .exe file.

A debugger is a program which allows you to load your object code program into system memory, execute the program and troubleshoot or debug it. The debugger also allows you to look at the contents of registers and memory locations after you run your program.

The debugger allows you to change the contents of registers & memory locations and rerun the program. Also, if facilitates to set up breakpoints in your program, single step feature,

and other easy-to-use features. If you are using a prototype SDK 86 board, the debugger is usually called monitor program. We would be using the development tool MASM 5.0 or higher version from Microsoft Inc. MASM stands for Microsoft Macro Assembler. Another assembler TASM (Turbo Assembler) from Borland Inc., is also available.

How to Write and execute your ALP using MASM?

Steps to be followed:

1. Type EDIT at the command prompt (C :\> \MASM\). A window will be opened with all the

options like File, Edit etc., In the workspace, type your program according to the assembly language syntax and save the file with a .asm extension. (say test.asm)

2. Exit the Editor using File menu or pressing ALT + F + X.

3. At the prompt, type the command MASM followed by filename.asm (say, test.asm). Press Enter key 2 or 3 times. The assembler checks the syntax of your program and creates .obj

file, if there are no errors. Otherwise, it indicates the error with line numbers. You have to correct the errors by opening your file with EDIT command and changing your instructions. Come back to DOS prompt and again assemble your program using MASM command. This

Mp and Mc Lab(17CSL48)

MSEC CSE Dept, Prepared By Nagayya S Hiremath Page 8 has to continue until MASM displays 0 Severe Errors. There may still be Warning Errors.

Try to correct them also.

4. Once you get the .obj file from step 3, you have to create the.exe file. At the prompt, type

the command LINK followed by filename.obj (say, test.obj) and press Enter key. (Note that you have to give the extension now as .obj and not as .asm). If there are no linker errors, linker will create .exe file of your program. Now, your program is ready to run.

5. There are two ways to run your program.

a) If your program accepts user inputs thro keyboard and displays the result on the screen, then you can type the name of the file at the prompt and press Enter key. Appropriate messages will be displayed.

b) If your program works with memory data and if you really want to know the contents of registers, flags, memory locations assigned, opcodes etc., then type CV test (file name) at the prompt. Another window will be opened with your program, machine codes, register contents etc., Now, you also get a prompt > sign within CV window. Here you can use d command to

display memory contents, E command to enter data into memory and g command to execute your program. Also, you can single step through your program using the menu options. In many ways, CV (Code View) is like Turbo C environment. Once you are familiar with the architecture and basics of assembly language tools, you can start typing and executing your program.
